Yes. When we're cloning a system, such as a compute node in a cluster, or rsync upgrading, we rsync -HPavxz /. newmachine:/new/.

I have a 1.5TB Western Digital hard disk (WD15EADS-00R6B0) on my CentOS-5.7 server, which has become incredibly slow for some operations, eg rsync, BackupPC archive, e2fsck, although it seems to work fine for ordinary file operations, and "smartctl -a /dev/sdb" does not report any errors. For example, running "e2fsck -p /dev/sdb5" on a 250GB partition on this disk took over 24

Last week I had a hard disk failure on my CentOS server. I managed to re-install CentOS on a new disk. I have the old mysql databases from /var/lib/mysql . Can I just move them to my new disk?

Has anybody successfully installed CentOS- I tried (several times) installing CentOS-5.6 from a hard disk, and each time it failed after installing all the rpms, with the warning "The installation has tried to mount image #2, but cannot find it on the hard drive." When I pressed the Debug button one time after the failure, it seemed to say that it was looking for the file in

Does anyone have experience of drupal installation under CentoOS-5.3 with MySQL database preferably accessed through phpMyAdmin. I want to install drupal more or less as an experiment, and I'm looking for a 1- or 2-page document that just lists precisely what steps to take. I've had a quick look at the official installation instructions, and I found them confusing and contradictory. --

I have a 1.5TB internal disk on my server. I partitioned this with fdisk, and CentOS-5.6 runs perfectly on it. But fdisk gives a very strange report. Here is the perfectly normal response to mount: ----------------------------- /dev/sdb10 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/sdb2 on /boot type ext3

Hi, I am about to spend one week of my holidays with transfering our (about 20 clients) NT4 domain to a AD DC one. We are running a samba NT4 PDC on debian buster which is offering dns (bind9) and dhcp (isc-dhcpd), too. I have an older server where I can play with an AD DC setup. If I see I won't make it in a week, I would like to be able to return as smooth as possible to the present

dear All, I'm facing this routing problem, the setup is actualy part of ltsp, but I think this problem is Centos-specific. The server is a Dell Poweredge R210. The install is standard 6.4, updated.

I''ve been monitoring the lists for a while now but didn''t see this problem mentioned in particular: I''ve got a fairly standard desktop system at home, 700gb WD drive, nothing special, with 2 btrfs filesystems and some snapshots. The system runs for days, and I''ve noticed unusual disk activity the other evening - turns out that it''s taking forever to

Hello, We have MySQL running as a master which is replicating to a single slave server. We are, however, considering what is required when a 'disaster' of some sort happens to either server. By disaster, this could be some event which requires the entire server to be rebuilt, and which would usually include restoring from nightly backups directories such as '/var/lib/mysql' and

Hi everyone, I made a utility tool for dm-ioband version 0.0.4, named iobandctl. It enables you to easily apply I/O bandwidth control to an entire disk, and manage it. It helps you set the percentage of bandwidth to give each partition, and each user, process, group, or cgroup. (You are not able to use cgroup support yet, because the dm-ioband patch to enable cgroup support
